Abstract

PURPOSE:To elevate the reliability of cap transfer by using a magazine which is made of two plates being placed face to face and cap taking-out rails wherein many cap insertion grooves are provided. CONSTITUTION:Rectified caps 1 are supplied to a chute 3 and these become free fall halfway and fall down into a magazine 4. The magazine 4 is constituted of two plates and guides 4c on both sides, and the caps 1 which have fallen into the magazine 4 are charged one after another from bottom with cap taking- out rails 6 as bottom and with the guides 4c as guides, and are inserted successively into cap insertion grooves 6a at the rails 6. And when the rails shift laterally while being guided by a slide 7, the caps 7 are taken out from the magazine 4. Hereafter, the caps 1 return to the magazine 4 again. At this time, the caps 1 are transferred to the grooves 6a. This way, by supplying and charging the caps 1 to the magazine 4 the reliability of transfer improves.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a terminal cap supply device for electronic components such as resistors and capacitors, which are constructed by press-fitting terminal caps to both ends of a cylindrical element body. It is.

Conventional technology Electronic components with terminal caps have been widely used in the past, and leadless resistors have also been put into practical use, and the manufacturing of such electronic components requires reliability and is becoming increasingly unmanned. There are also demands for response.

Conventionally, this type of terminal cap supply device, as shown in Japanese Patent Publication No. 58-31723, transfers caps one by one from a vertical stacking chute to a rolling wheel with a groove around the circumference and moves on to the next process. It was meant to be transported. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a conventional terminal cap supplying device for electronic components as described above will be explained with reference to the drawings.

FIG. 4 shows a conventional terminal cap supply device for electronic components. In FIG. 4, 1 is a cap, 9 is a chute, 1o is a cap conveying roller, and a large number of cap insertion grooves 11 are provided on the outer periphery. 13 is a rotating shaft, and 12 is a guide.

A conventional terminal cap supplying device for electronic components will be described below with reference to FIG. The caps 1 are fed vertically through a chute 9. Note that this chute 9 guides the cap 1 in four directions and regulates misalignment with the cap insertion groove 11 of the cap conveying roller 10. Then, when the cap conveying wheel 10 rotates around the rotating shaft 13 and the positions of the cap insertion groove 11 on the outer periphery and the chute 9 match, the cap 1 is transferred by its own weight.

The transferred cap 1 is then transported to the next process while being prevented from popping out by the guide 12.

Problems to be Solved by the Invention However, the conventional configuration has the following drawbacks. First, since the caps 1 are transferred one by one from the chute 9 which is regulated in four directions to the cap insertion groove 11 of the cap conveying roller 1o, high positioning accuracy in the rotational direction is required.

Furthermore, if an attempt is made to increase the supply speed, the transfer positions are limited, making it difficult to take sufficient time for transfer, resulting in clogging and lowering the reliability of the equipment. However, if the supply quantity is increased by increasing the number of pieces, the above-mentioned positioning accuracy will be further required and the apparatus will become complicated. Furthermore, in the supply system up to the chute 9, if an attempt was made to provide a buffer amount in order to minimize equipment stoppage, there was a drawback that the storage device, which is a vertical stacking chute, would become large.

As described above, conventional terminal cap supply apparatuses have had many problems in terms of the high supply speed and high reliability of cap transfer, which are required of terminal cap supply apparatuses in the future.

In view of the above-mentioned drawbacks, the present invention provides a terminal cap supplying device for electronic components that improves the reliability of camp supply, enables unmanned operation, and has several times the supply capacity of conventional equipment.

Means for Solving the Problem In order to solve this problem, the terminal cap supplying device for electronic components of the present invention has a chute that regulates only the thickness direction of the cap and leaves it free in the width direction, and two plates below the chute. The magazine is comprised of a magazine formed by guides on both sides to regulate only the thickness direction of the cap, and a cap ejection rail having a number of cap insertion grooves provided at the bottom of the magazine.

Function: With this configuration, the cap first falls down the chute without regulating the width direction, and then falls into the gap in the magazine. At this time, since only the thickness direction of the cap is regulated and the width direction is free, clogging is almost eliminated.
, and high-speed supply is possible. Next, the caps that have fallen into the gap in the magazine are filled into the magazine from the bottom, with the cap take-out rail as the bottom surface. After the caps are sufficiently filled, the caps are successively dropped into the cap insertion groove by laterally moving the cap removal rail. This allows for more time to fall into the groove than before, and since the caps to be inserted are not fixed but an unspecified number of targets, the probability of insertion is much higher than before1. Sometimes, since there is no regulation in the thickness direction, the degree of freedom of the cap increases, making it easier to insert and having a structure that is less likely to clog. Furthermore, it is possible to transfer the caps and caps to the rails almost simultaneously using a large number of grooves, and by changing the number of grooves and the width of the magazine, it is possible to supply a large number of caps at the same time.

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of a terminal cap supply device for electronic components in one embodiment of the present invention. In FIG. 1, 1 is a cap, 2 is a parts feeder, and 3 is a chute from the parts feeder 2 to the magazine 4. The chute 3 has an arc shape. Further, as shown in FIG. 3, the height of the inside of the chute 3 is slightly larger than the thickness of the cap 1, and the width thereof is several times that of the cap 1. The magazine 4 has a front plate 4a.

It is composed of two plates, the rear plate 4b, and guides 4C on both sides. The front plate 4a is made of transparent resin or glass so that the filling condition of the cap 1 can be seen. The gap between the two plates, the front plate 4a and the rear plate 4b, is determined by the thickness of the guide 4C, and this amount is slightly wider than the thickness of the cap 1, as shown in FIG. 5 controls the filling amount of camp 1 with a phototube. Reference numeral 6 denotes a cap ejection rail, and cap insertion grooves 6a are provided at regular intervals on the upper surface. The thickness of the cap ejecting rail 6 is about the same as that of the camp 1, and the cap insertion groove 62L portion is sandwiched between the two plates of the magazine 4. Further, the length of the cap take-out rail 6 is set to be 40 times the length of the magazine so that the cap 1 in the magazine 4 does not fall even when the cap 1 is taken out. FIG. 2 shows the main parts of the magazine 4 and the cap take-out rail 6.

Here, the depth of the gap insertion groove 6a is approximately the same as that of the cap 1, and the groove shape may be such that the entrances are parallel, but it is possible to increase the probability of insertion by using shapes with various sizes. The cap insertion groove θ is still in place to assist in falling into the cap insertion groove 6a and to prevent the cap from popping out when the cap ejection rail 6 comes out from the magazine 4.
A vacuum hole 6b is provided at the bottom of &. Note that the prevention of popping out may be achieved by using a guide or magnetic force. In FIG. 1, 7 is a slide. This serves as a guide when the cap take-out rail 6 moves in and out of the magazine 4.

The operation of the electronic component terminal cap supplying device configured as described above will be described below.

First, the parts feeder 2 supplies the caps 1 aligned in a fixed direction to the shoes 1-3.

Since the chute 3 has an arcuate shape, the chute 3 freely falls from the middle and falls into the magazine 4. Since the chute 3 only regulates the thickness direction of the camp 1, there is freedom in the width direction and fall direction inside, so clogging hardly occurs. Then, the cap 1 that has fallen into the magazine 4 has the cap ejection rail 6 as the bottom surface, and the guides 4 on both sides.
Filling is performed sequentially from the bottom using C as a guide. Then, when a certain amount is reached by the phototube 5, the supply of the parts feeder 2 is automatically stopped. Also magazine 4
Camp 1 filled with cap, cap removal L/-6
are inserted into the cap insertion groove eaQ one after another. When the cap take-out rail 6 moves laterally while being guided by the slide 7, the camp 1 is taken out from the magazine 4. At this time, the vacuum hole 6b prevents the gap 1 from popping out3.After this, in the next step, the camp 1 is taken out from the cap insertion groove 6a and then returned to the magazine 4. At this time, the camp 1 is transferred to the cap insertion groove 6a of the cap removal rail 6.

By repeating this lateral movement of the cap take-out rail 6, the caps 1 are successively supplied. In addition, if a device symmetrical to the present device is installed horizontally and one is used to supply the cap and the other is operated repeatedly to transfer the cap, very efficient cap supply becomes possible.

As described above, according to this embodiment, the reliability of transfer is increased by supplying and filling the cap 1 into the chute 3 and the magazine 4, which have a high degree of freedom.

In addition, since the magazine method transfers the gap 1 from a place where there is a sufficient buffer, and the transfer time can be long, stable supply can be achieved.

In terms of supply speed, the conventional rolling wheel system was only able to supply 74 pieces per minute, whereas the magazine system allows stable supply at over 2000 pieces per minute. Furthermore, since the amount of caps supplied by the parts feeder 2 is controlled, the device requires almost no maintenance and is fully compatible with unmanned production.

Effects of the Invention As described above, the present invention provides a magazine with a high degree of freedom in regulating the camp only in the thickness direction, and furthermore uses a cap ejection rail with a large number of cap insertion grooves for ejecting the cap. The reliability of transferring caps is dramatically improved compared to the conventional method, and a large number of caps can be supplied simultaneously and at high speed, which has great practical effects.
